		# 快应用卡片表达式解析

		## 快速上手
		用于将 `JS表达式` 转换为 `快应用卡片表达式`

		```js
		import translateJsToCardCode from '@aiot-toolkit/card-expression';
		快应用卡片表达式是一种类似 `lisp的语法树表达式`

		const code = 'a+b';
		const result = translateJsToCardCode(code);
		console.log(result);
		```

		## 转换流程
		\| 表达式 \| 转换后 \|
		\| ---------------- \| --------------------------------------------------------- \|
		\| `a+123` \| `['+', ['$', 'a'], 123]` \|
		\| `!a` \| `['!', ['$', 'a']]` \|
		\| `a[1].x.y` \| `['.',['.', ['.', ['$', 'a'], 1], ['$''x']], ['$', 'y']]` \|
		\| `fun(a, b, 124)` \| `[['()', ['$', 'fun'], ['$', 'a'], ['$', 'b'], 124]` \|

		转换流程由以下 3 步组成，每步可单独使用
		## 快速上手

		1. JS 代码转换为 JS ast 树
		### js 代码转为 Card 代码

		```js
		const jsNode = new JsExpressionParser().parser(code);
		```
		import translateJsToCardCode from '@aiot-toolkit/card-expression';

		2. js ast 树转换为 Card 对象

		```js
		const cardNode = new JsNodeToCardNode().translate(jsNode);
		const code = 'a+b';
		const result = translateJsToCardCode(code);
		console.log(result); // '["+", ["$", "a"], ["$", "b"]]'
		```

		3. Card 转换为 Card 代码

		```js
		const cardCode = new CardNodeGenerator().generator(cardNode);
		```
